General Motors has officially commenced production of the 2027 Chevrolet Silverado and GMC Sierra trucks at its plant in Silao, Mexico. Customers are expected to begin receiving the first of these new vehicles within the next two months.
Why it matters
The launch marks a critical update to General Motors' core truck lineup as the company looks to maintain a streak of 19 consecutive quarters of U.S. sales leadership. The rollout aims to build on recent sales momentum that saw combined Silverado and Sierra figures grow by 9% in the third quarter of 2026.
The trucks feature a 10-speed automatic transmission and a powertrain lineup including 5.7-liter and 6.6-liter V8 engines, a 2.7-liter TurboMax engine, and a 3.0-liter Duramax diesel. Sales of the current light-duty Silverado increased 6% through September.
